ATTORNEY United States Patent 3,286,293 STOP NIEANS FOR GUN CLEANING DEVICE Charles F. Eckert, 1109 Devereaux St., Philadelphia, Pa. Filed Mar. 9, 1965, Ser. No. 438,225 8 Claims. (Cl. 15104.16)

The invention relates to a stop means for gun cleaning devices, and more particularly to a stop means for elongated rod type of cleaning devices for guns.

In using the rod type of cleaning device in which a brush or cleaning patch is secured with the end of the rod, the unrestricted travel of the rod through the bore of the gun may result in damage to the gun mechanism, cause the loss of the cleaning patch within the gun, and increase the difliculty of performing the cleaning operation,

Therefore, it is a principal object of the invention to provide a new and improved stop means for gun cleaning device which limits the cleaning rod travel and minimizes damage to the gun.

Another object of the invention is to provide a new and improved stop means for a gun cleaning device which prevents the cleaning rod tip or brush from damaging the delicate gun parts, such as the extractor, ejector, and firing pin.

Another object of the invention is to provide a new and improved stop means for a gun cleaning device which prevents damage to the rod tips and brushes, and prevents patches from falling off the rod tip.

Another object of the invention is to provide a new and improved stop means for a gun cleaning device, which permits faster and more efiicient cleaning of guns by using rod means and preventing over-travel and overstroke past the end of the barrel.

Another object of the invention is to provide a new and improved stop means for a gun cleaning device which has a non-marring face which prevents damage to the gun muzzle.

Another object of the invention is to provide a new and improved stop means for a gun cleaning device which can be adjustably locked at any position along the cleaning rod to adjust to the barrel length of the gun being cleaned.

Another object of the invention is to provide a new and improved stop means for a gun cleaning device having various rod diameters for cleaning various caliber guns.

Another object of the invention is to provide a new and improved stop means for a gun cleaning rod which may be used with any presently available cleaning rod and can be used at the muzzle end of a gun or where access permits at the breach and chamber end of the barrel. I

Another object of the invention is to provide a new and improved stop means for a gun cleaning device which may be easily and inexpensively produced and is of high durability.

The above objects as well as many other objects of the invention are achieved by providing a stop means for gun cleaning device comprising a body having an opening therethrough for receiving the rod of the cleaning device and a front surface, a protective washer unit positioned along the front surface of the body for contacting the muzzle end of a gun, and locking means received within said body for detachably securing said body with the rod.

Another form of the stop means comprises a body having an opening therethrough and a front surface, an insert unit having a central portion with an opening therethrough for receiving the rod of a gun cleaning device and a front portion, the central portion of said unit being received into the opening of said body with its front portion positioned proximate the front surface of. said body for contacting the muzzle end of a gun, and locking means comprising a screw clamping element extending through said body and said unit for securing same together and with said rod.

A further form of the stop means comprises a body having an opening therethrough and a front surface, an insert unit having a central portion with an opening therethrough and a front portion, the central portion of said unit being received into the opening of said body with its front portion positioned proximate the front surface of said body for contacting the muzzle end of a gun, a'plurality of sleeve units telescopically received within one another and within the opening of said insert unit and being selectively removable to provide an opening dimensioned to receive the rod of a cleaning device, and locking means comprising a screw clamping element extending through said body and said units for securing same together and with said rod.

The foregoing and other objects of the invention will become more apparent as the following detailed description of the invention is read in conjunction with the drawings, in which:

FIGURE 7 is a perspective view of a modified form of stop means,

FIGURE 8 is a sectional view taken along the line 88 of FIGURE 7, and

FIGURE 9 is an exploded view of the stop means shown in FIGURE 7.

Like reference numerals designate like parts throughout the several views,

FIGURES 1 through 4 disclose the stop means 10 embodying the invention, including a body 12 in the form of a ring which may be made of metallic material such as steel. The body 12 has an opening 14 therethrough, front and rear surfaces 16 and 18, and an outer peripheral surface 20.

An insert unit 22 which may be made of a synthetic plastic material such as polyethylene, pylon or Teflon has a central portion 24 which is received within the opening 14 of the body 12, and a front portion 26 which is received and positioned proximate the front surface 16 of the body 12. The insert unit 22 has an opening 28,

therethrough for receiving the rod 30 of a gun cleaning device 32.

A clamping means is provided by a screw element 34 which threadedly engages the body 12 at its radially extending opening 36 and extends through an aligned opening 38 in the insert unit 22 for clampingly engaging at itsend 40 the rod 30 of the device 32. The screw element 34 while passing through the openings 36 and 38 respectively of the body 12 and insert unit 22 also serves to respectively position and retain together the body 12 and insert 22.

In use the screw element 34 is retracted or withdrawn to allow the rod 30 of the cleaning device 32 to be slideably received through the opening 28 of the insert unit 22. The stop means 10 is positioned along the I length of the rod 32 and secured therewith by tighten-ing,

the screw element 34 at a location which allows the cleaning element or brush 42 to extend the entire length of the barrel 4% of a gun 46 which is to be cleaned when the stop element 10 has its front surface 48 engage the ends 50 of the muzzle 52 of the gun 46 shown in dashed lines in FIGURE 1.

The rod 30 of the gun cleaning device 32 is provided with a handle 54 at one end and a pivotally connected rod section 56 at the other end of standard construction. The pivotal section 56 may be threadily attached to the brush 42 or receive a patch thereabout for cleaning the bore 44 of the gun 46. When the stop means 10 is properly secured in position on the rod 30 of the cleaning device 32, the end of the rod section 56 when a patch is being used or the end of the brush 42 when it is attached, extends through the barrel 44 of a gun 46 to the end of the barrel 44, but is prevented by the stop means 10 from extending any further and damaging the delicate mechanism of the :gun.

The end 50 of the muzzle is not damaged when struck by the front surface 48 of the insert unit 22 of the stop means 10 because of the relatively resilient plastic material of which the insert unit 22 is composed. The cleaning device 32 thus may have its rod 30 briskly actuated in a reciprocating motion striking the front surface 48 of the insert 22 for cleaning the bar-rel 44 of the gun 46 without over-extending the rod 30 into the gun 46 and damaging its mechanism. Also, when a patch is being used at the end section 56 of the rod 30, the end 56 is not over-extended through the barrel 44 of the gun 46, so that the patch is not displaced from the end of section 56 but remains positioned thereon during the entire reciprocating cleaning action.

When a cleaning device 32 is to be used with a rod 30' having an enlarged diameter, the insert unit 22 of the stop means 10 may be replaced by an insert unit 22 (shown in FIGURE 4) provided with a larger opening 28 therethrough. The insert unit 22 is readily removed from the body 20 by retracting the threaded element 34 removing its end 40 from the opening 38 in the unit 22. After the unit 22 is replaced by the unit 22, the element 34 may again be rotated to have its ends 40 received into the opening 38' for securing the insert 22 in position with the body 12 of the stop means 10. A plurality of such insert units 22 and 22' may be provided with various openings 23 and 28' therethrou-gh for accommodating different diameter rods 36 and 30 of the cleaning device 32.

FIGURES and 6 disclose a modified form of stop device 56 comprising a body 58 which may be made of metallic material such as steel provided with an opening 60 therethro-ug'h for receiving the rod 30 of a gun cleaning device 32. The body 58 has a front surface 62, a rear surface 64, and an outer peripheral surface 66 providing the body 56 with a cylindrical configuration. A washer unit 68 which may be made of a felt, soft metal or plastic material is positioned proximate the front surface 62 of the body 58 and has a central opening 70 in alignment with the opening 60 through the body 58.

The body 58 is provided with a radially extended opening 72 which th-readily receives therein a screw clamping element 74.

In operation, the stop means 56 is positioned and retained along the rod 30 of the gun cleaning device 32 by tightening the screw element 74 and acts in a manner similar to that described in connection with the device to limit the inward moment of the rod 30 into the barrel of a gun. The washer unit 62 being made of a relatively soft material, serves to prevent damage to the end of the gun muzzle when the stop means 56 engages the gun when the rod is being thrust into its barrel.

FIGURES 7, 8 and 9 disclose a modified form of stop means '76 comprising a cylindrical body 78 having an opening 80 theret'hrou-gh, front surface 82, rear surface 84 and a peripheral outer surface 86. The body 78 retained in position as shown in FIGURE 8.

may be made of metallic material such as steel and have a radially extending opening 88 for threadily receiving a screw clamping element W. The screw element 9% as illustrated may be provided with an Allen head.

An insert unit 92 which may be made of a plastic material such as polyethylene, nylon or Teflon, has an extending cenrtal portion 94 which is received into the opening 80 of the body 78, and a front portion 96 which is positioned proximate the front surface 82 of the body 78. 'Ilhe insert unit 92 is also provided with a radially extending opening 918 for receiving the screw clamping element 90 therethrough. The unit 92 is provided with an opening 1% therethrough which removably receives within it a sleeve element 102 similarly provided with an opening 104- t'herethrough and a radially extending opening 106 for receiving the clamping element 96 therethrough.

A removable sleeve element 168 of reduced diameter similar to the sleeve element 102 is .removably receivable into the opening 104 of the element 102, and is provided with a similar radially extended opening 119. An additional sleeve element 112 similar to the sleeve element 1% is removalby receivable into the opening 11 of the sleeve element 108 and provided with an axial opening therethrouigh 116 and a radial opening 118.

The sleeve units 102, 108 and 112 may be made of a plastic material similar to that of the insert unit 92, and are retained in position within one another and within the opening 100 of the insert unit 92 by the extension of the screw clamping element 9% through openings 98, 106, 1 10 and 118.

By use of the plurality of telescopically arranged insert and sleeve units, the stop means 76 allows the axial opening therethrough to be adjusted in diameter for accommodating rods 30 of gun cleaning devices 32 having various diameters. Thus, the smallest opening is provided by the stop means '76 with all of its sleeve units If a rod 30 having a larger diameter is to be used, one or more of the sleeve units 112, 108 and 102 may be removed in the order stated to progressively provide a larger opening through the stop means 76. The sleeve elements may be removed by threadily withdrawing the screw element 90 so that it disengages the respective radial openings 11-8, 110 and 106 of the sleeves 112, 108 and 162. The stop means 76 thereby provides a large range of cleaning devices of different sizes with which it can be used. After the stop means 76 is adjusted by removable replacement of its units 102, 108 and 112 provide the proper opening therethrough, the stop means 76 is positioned and secured with the rod 30 of the gun cleaning device 32 by tightening the clamping element 90,

i and may be used in the manner described above i connection with the stop means 10 and 56.

It will, of course, be understood that the description and drawings, herein contained, are illustrative merely, and that various modifications and changes may be made in the structure disclosed without departing from the spirit of the invention.
